WPF的DateGrid数据源问题

[py1025677845]

我用的是Nhibernate的到的是一个Ilist结果集，怎样去给DateGrid赋值，
也就是说怎么把数据库的数据读到DateGrid中去。

直接将这个List集合指定给该DataGrid的ItemsSource即可。

public class Person
    {
        public string Name { get; set; }
        public int Age { get; set; }
    }

 List<Person> list = new List<Person>();
            list.Add(new Person() { Name = "张三", Age = 22 });
            list.Add(new Person() { Name = "李四", Age = 22 });
            datagrid1.ItemsSource = list;

  <DataGrid Name="datagrid1">
            <DataGrid.Columns>
                <DataGridTemplateColumn Header="{Binding Name}" />
            </DataGrid.Columns>
        </DataGrid>

窗体加载事件
private void Window_Loaded(object sender, RoutedEventArgs e)
{
IList<Stuinfo> list = dao.getAll();
this.dataGrid1.ItemsSource = list;

}
可是怎么不能啊

[ustbwuyi]

你把list的count弹出来看下有几条数据。你确定有数据？

[龍过鸡年]

AutoGenerateColumns="True" 貌似不需要再定义 Columns 了吧

还有，报什么错呢？ dao.getAll() 是什么？

AutoGenerateColumns="True" 应该改成False。

不过你数据不显示不是这个问题，应该是你取数据有问题。

[py1025677845]

public static ISessionFactory getSessionFactory()
{
1 Configuration cf= new Configuration().Configure("hibernate.cfg.xml");
2 factory = cf.BuildSessionFactory();
3 return factory;
}
1那里出问题了 The invocation of the constructor on type 'Stu_WPF.MainWindow' that matches the specified binding constraints threw an exception.' Line number '3' and line position '9'.

[py1025677845]

public IList<Stuinfo> getAll()
{
ISession session = factory.OpenSession();
IList<Stuinfo> list = session.CreateQuery("from Stuinfo").List<Stuinfo>();
return list;
}

[ustbwuyi]

那就是你使用hibernate有问题了。
